Canon R3 Review: My Perfect Camera

Nice personal report on the R3.
I can agree on many points. The R3 is also for me in many points superior to the current models of Sony A1 and Nikon Z9, if you do not put the emphasis on MP😉.

For me, the eye control is a real game changer and works flawlessly. It's an intuitive tool when shooting sports, especially team sports, and I wouldn't want to be without it. In low light situations, the AF is also much better than Sony and Nikon in my experience and focus on the eye of people where the A1 still has to search for a long time, or not even find the eye of a person.
As for the Nikon, I can only report from a colleague's test where we directly compared both cameras - last week in the evening.
The Z9 had a hard time finding a person's eye in some lighting conditions, for example when shooting people under neon tubes that were only in the background at a height of 3 meters, while the R3 had no problem finding the eye at all.
Personally, however, the Z9 would also be too heavy and unwieldy for me. Although I might also like the more MP - but at the moment I don't miss it.

I find it interesting that the AF on the Sony a1 and the R3 are almost on par when tracking fast moving subjects under normal lighting conditions. The hit rate is impressive and is at the highest level. Sometimes the A1's higher crop capability with smaller subjects, using the same focal lengths and speed of the respective manufacturer's lenses, is an advantage of Sony's a1.

The battery life is comparable to the Sony a7iv. So I can report that the battery meets normal demands, but doesn't knock me off my feet at all.
I'm also not entirely happy with the chromatic aberration in the viewfinder - had written about this in the forum some time ago - unfortunately neither received any assured feedback from Canon, nor could I take a photo of the viewfinder with high-contrast subjects.
Very small points of criticism are, in addition to the shutter noise in Single Shot in E-Shutter mode, which is no different from the noise of a continuous shooting - an "electronic click" would be a dream, also the issue of "colored viewfinder field". I would like to see a different color for the viewfinder field as well. Because this is not always easy to make out.
Both small problems could certainly be changed via a software update...

Apart from the viewfinder issue, the shutter noise and the viewfinder field, the camera is almost perfect for me.
